Previous campaigns have targeted insurance premiums and energy costs, but this is the first time the company has targeted fuel prices.
The company had initially set a three-week target to achieve around $1 million worth of ‘buying power’, measured in terms of the number of motorists it could sign up and the amount of fuel they plan to purchase.
The target was met within three hours.
Now into its second day, the campaign has already secured $8 million worth of buying power, as more than 40,000 motorists have registered their interests.
Previous campaigns have seen as little as 10 percent of initial respondents follow through with their commitment once a bulk-buying deal is finalised, but One Big Switch found that other retailers were forced to offer more competitive prices regardless.
The group hopes to negotiate a five percent discount for its members using pre-paid fuel cards; or a saving of around 7.5 cents per litre off a fuel price of $1.50 per litre.
Industry factors however, such as the planned BP refinery closure in Brisbane have put upward pressure on fuel prices, with the average price doubling since 2002.
One Big Switch says registration for the campaign is entirely obligation-free and free of charge, with pre-registration closing on June 20, 2014.
